Different types of bacteria, viruses, cysts, and parasites can make their way into your drinking water if it is not filtered properly. Shockingly, there often are several kinds of these things swimming in your glass. While most of these are not dangerous, there are some that are. The ones that are dangerous can present some great health and safety risks. Now that you know that what may be in our water, what does this mean? What are bacterias, viruses, and parasites and what is the difference between them?


Bactria, viruses, and parasites all have something in common and that is that they are all microbes. Microbes are tiny microorganisms that exist all over the place. While they are often classified as being dangerous, this is not always the case. Although they are all around us, they are so small that they are impossible to see with the naked eye. The most common types of microbes are viruses, bacterias, and fungi.


Bacteria is an organism made up of a single cell. They live almost everywhere on earth. They have cell walls but lack other common cell parts such as a nucleus. There are several different types of bacteria some of which are helpful to humans and some that are harmful. They are decomposers meaning they break down the waste of other organisms or their dead bodies to make their components available for reuse.


Unlike bacteria, viruses do not actually have any cells of their own. They are simply one or more molecules inside of a protein shell. They cause nothing but harm in organisms and can only reproduce and spread inside a living organism. While some do not cause any more harm than a mere cold, others are responsible for sicknesses much more deadly such as AIDS. These little microbes are to blame for disease and sickness.


A parasite is an organism that lives inside of another, using it as a host. It often is harmful to the host and depends on it for survival. It can only grow and multiply with the help of a host. Therefore, when a parasite is inside the host, it can thrive at the expense of the other. A parasite is similar to a predator but different. Unlike a predator, a parasite will rarely kill the host because they depend on it for their own survival. They are also much smaller than the host and reproduce rapidly.
